Re: In The Old Days
i owned a 59,62,63,64,65 and a 66 corvettes all new and never had any paint problems. they had a lot less "orange peel" than my C-5s -
Re: In The Old Days
Blistering is caused by filler lifting or osmosis through old fiberglass. Not something you'd see with new cars but more typical of car repaired and repainted.Comment

Clem:
Maybe spidering, checking, which is common, but no blistering. I am implying a problem with the composite, but not the lacquer.
Thanks,

Re: In The Old Days
I've had 23 Corvettes. None of the 18 sharks and mid-years ever had a blistering problem.

Yes, when done by a bad painter. *NM*

Don't Condemn The Painter...........
......because the problem might lie with the manufacturer of the replacement panels. I refuse to point the finger until I determine the cause of the problem.

Agreed, don't rush to judgement...
Now we're talking. We know the problem is in the replacement panel, correct? Were the panels press molded or hand laid? Were they gel coated. Were they ever repainted or repaired after the intital installation? Could be osmosis through the panel.Comment

Re: Agreed, don't rush to judgement...
Clare:
The panels are brand new reproductions, press moulded, and not gelcoated (as OEM). I am trying to determine the cause of the problem, but this should not be my responsibility. I only want to get my car "right", without any litigation. I think like a technocrat, and so I only look to solve the problem, and let the lawyers be damned.Comment

osmosis thru the panel?
Is there a moisture source on the other side of the panel?
Before you think I'm trying to fill in for Todd H., I think I can see where both your question about hand laid vs injection molded and the one about repair are leading, but I've never heard that ambient humidity is enough to pass thru a fiberglass panel - especially in enough quantity to blister paint on the other side.Comment

You asked a simple question - did Corvette
paint ever blister in the old days? The answer is yes, when done by a painter who doidn't know what he was doing, did not have charge of the preparation of the surface. etc. In short the answer to what you asked is YES. There was nothing in your question about panels.Comment

Re: osmosis thru the panel?
Ralph,
-------Osmosis can be more than humidity. Matter of fact,I personally dont think water can get thru gel-coated,press-molded panels,at least not easily. On the other hand oil can find its way thru fiberglass. I have seen many air cond. cars that have had oil osmosis thru the hood above the ac pulley which is a common oil oozer for want of a better term. Also up thru the floor on occasion. To be corrected you almost have to replace the affected panel or at least the affected area.
-------No one has addressed the problems the fellas in Oregon had several years ago (circa 1994/5) with their press-molded products. I bought a turn-signal panel and scoop panel that,after painting,blistered in short order. Im far from the only one who had problems. Many had far worse than me. As far as I know they solved their problem. There was a reason for the blistering,but after all this time I cant remember exactly what it was........Bill SComment

Re: In The Old Days
I have read (Corvette Fever?) that the StLouis factory had a paint shop with 225% capacity, because it wasn't unusual for the filler to blister coming out of the ovens - and a lot of cars had to make more than two trips through the paint shop.Comment

Re: In The Old Days
LOTS of Corvettes made two or more passes through the old St. Louis paint shop, mostly due to "solvent-popping", especially in the exposed bond seams; bond seams were always a big problem. Even when they finally got an OK at the end of the paint shop, some would show more new pops at the end of the line, and took a pass through Final Paint Repair as completed cars. Very few Corvettes didn't get at least SOME work in Final Paint Repair; good thing they were lacquer and spot-repairs and "blow-ins" were easy to do, with lots of polishing.Comment

Time heals.....maybe
It sounds like you guys are talking about Corvette Image panels. Their paint blistering is a tough problem to lick. As for their advice to gel-coat everything.... I don't think so. I'm not building boats here.
I've got one of their hood surrounds out in the sun now. It's out there "cooking off" any contaminants. After another year or two I'm going to spray it with lacquer and see what happens. My theory is that all the orange stuff should eventually leech out of the bare panel in the southern heat. We'll see. It began as white fiberglass and now it's turned a light pink color. You don't think I've sun-burned it, do you?Comment
